Installation Installing the Air System on Your Aircraft 1. Prepare the two Air System antennas and some double-sided foam tape. 2. Insert the antennas into the ports on the side of the Air System and snap into place.

Installation

3. Use the foam tape to mount the Air System onto the reserved space of your aircraft or other suitable flat surfaces. Install the antennas before powering on the Air System. For optimal transmission quality, point the antennas downwards and avoid obstruction from other onboard equipment. Only use official DJI antennas and ensure they are installed correctly. When connecting the antennas, ensure the connector pin is aligned with the port hole, and DO NOT apply excessive force to avoid damaging the pin. Only remove the antennas from the Air System unless it is absolutely necessary. When removing the antennas, use pliers to grip the metal connector, and DO NOT apply force to the wire. For larger aircrafts, use an extension cable to connect the antennas to the Air System. The DJI Spreading Wings series come with an antenna mount which is used to position the antennas perpendicular to the landing gear. Watch the video tutorials on the official DJI website for more details.

Connecting the Ground System to Your Display Device Select one of the video ports on the Ground System to output to your display device: SDI – Connect your SDI monitor to the Ground System using an SDI cable. HDMI – Connect your HDMI monitor to the Ground System using an HDMI cable.


15

DJI Lightbridge 2 User Manual USB – Mount your mobile device onto the Mobile Device Holder and connect it to the Ground System using a USB cable. Launch the DJI GO app to access video and flight telemetry. The SDI or HDMI cable can be attached to the Ground System handle using the Wire Clip (optional accessory). The SDI and HDMI ports on the Ground System cannot be used together.

Below is an illustration using the USB video output. Please prepare a slotted screwdriver. Install the Mobile Device Holder: Installation

1. Unfold the Mobile Device Holder

. Remove the screw using the slotted screwdriver

.

2. Plug the Mobile Device Holder into the Ground System and tighten the Screw Lock. 3. Line up the hole on the Mobile Device Holder with the metal loop on the Ground System. Insert and tighten the screw.

Standard Configurations This section provides examples and way to configure Lightbridge 2. Choose the configuration that best fits your needs.

Air System - DJI HD Gimbal + DJI Flight Controller

When used with a DJI HD gimbal, you can select either single or dual video source mode in the DJI GO app. In single video source mode, the Air System transmits either the gimbal camera video or FPV camera signal to the Ground System. In dual video source mode, both signals are transmitted by the Air System.

1. Connect the gimbal port on the Air System to the G7 port on the DJI HD gimbal and the CAN BUS port on the flight controller. 2. Connect the HDMI or AV port on the Air System to the FPV camera. 3. Connect the DBUS port on the Air System to the DBUS port (X2 port) on the flight controller with the DBUS cable. 4. Refer to the user manuals for the gimbal and flight controller for details. Only use the DJI HD gimbal and DJI flight controller with the latest firmware. If you are using the DJI A2 Flight Controller, connect the gimbal cable to the CAN 2 port on the controller unit. A CAN-HUB is recommended to provide extra CAN ports, if there is not enough CAN port.

Below is an illustration of the DJI HD gimbal connected to the DJI A2 Flight Controller.

DJI Lightbridge 2 User Manual Ground System - Dual Ground Systems Mode

More than one Ground System can connect to the same aircraft in Dual Ground System Mode. In Dual Ground System Mode, the Master Ground System controls the movement of the aircraft, while the Slave Ground System controls the movement of the gimbal and camera. When multiple Slave Ground Systems (max of 3) are connected to the aircraft, only the first connected Slave Ground System is able to control the gimbal. The remaining slave Ground System can view the live feed video from the aircraft, but they cannot control the gimbal.

Installation Master Ground System

Slave Ground System

The gimbal dial on the Master Ground System controls the pitch motion of the camera. In Dual Ground System Mode, the Slave Ground System can be used to control the roll and yaw motions of the camera.

18


Ground System The Ground System features a number of standard interfaces intended for aircraft and camera control, which are explained below with their most typical functions. However, you can remap these interfaces to the flight controller channels using the DJI Flight Controller Assistant. Compliance: The Ground System is compliant with both CE and FCC regulations. Control Stick Modes: Mode 1, Mode 2, or a customized mode. Mode 1: The right stick serves as the throttle. Mode 2: The left stick serves as the throttle. DO NOT operate more than 3 aircrafts within in the same area (size equivalent to a soccer field) to prevent signal interference. Ground System

Ground System Operations Using the Power Button

1. Press the power button once to display the current battery level. 2. Press again and hold to power on the Ground System. 3. The Status Indicator will blink green (blink purple for Slave Ground Systems) rapidly when the Ground System is linking to the Air System, and become solid green when the link is established. 4. Press the power button once, again, and hold to power off the Ground System.

Charging the Ground System

Only use the official DJI battery charger to charge the Ground System’s 6000mAh 2S built-in battery.

Power Outlet Charger

Ground System

Controlling the Aircraft

The following table describes the functions of the Ground System for the default settings - Mode 2. Stick Neutral/mid point: Control sticks of the Ground System are placed at the central position. Move the Stick: The control stick is pushed away from the central position.

Ground System (Mode 2)

Aircraft (

indicates nose direction)

Description Vertical movement of the left stick controls the aircraft’s elevation. Push up to ascend and press down to descend. Use the left stick to take off when the motors are spinning at idle speed. The aircraft will hover in place if the stick is in the neutral position.

Horizontal movement of the left stick controls the aircraft's heading. Move left to rotate the aircraft anticlockwise and move right to rotate the aircraft clockwise.

20



Vertical movement of the right stick controls the aircraft’s pitch. Push up to fly forwards and press down to fly backwards. Move the stick further for a larger pitch angle and faster flight. Horizontal movement of the right stick controls the aircraft’s roll. Move the stick Ground System

left to fly left and right to fly right. Move the stick further for a larger roll angle and faster flight.

Turn the Gimbal Dial to the right to tilt the camera up, and to the left to tilt the camera down.

Always push the control sticks gently to prevent sudden and unexpected movement of the aircraft. The aircraft can be stabilized when the control sticks are at mid point in P-mode or Atti mode. The aircraft cannot stabilize itself automatically in Manual mode, operate with caution.

DJI Lightbridge 2 User Manual P-mode (Positioning): The aircraft uses GPS for positioning. This mode works best when the GPS signal is strong.

Atti mode (Attitude): GPS is not used for positioning, and the aircraft only uses its barometer to maintain altitude. If a GPS signal is present, the aircraft will still return to the last recorded Home Point if the Ground System signal is lost. F-mode (Function): Acts as A-Mode (default) or Manual Mode for Lightbridge 2. Select the desired mode in the DJI Flight Controller Assistant.

Return-to-Home (RTH)

Press and hold the RTH Button to bring the aircraft back to the last recorded Home Point. The LED around the RTH Button will blink white during the RTH procedure. Refer to the flight Ground System

controller user manual for more information on how to regain control during RTH.

The DJI WooKong-M Flight Controller does not support the RTH feature.

Optimal Transmission Range

To achieve optimal transmission, separate the two antennas and adjust their positions so that the flat side faces the aircraft.

Optimal Transmission Range

If the transmission signal is weak, adjust the positions of the antennas and fly the aircraft closer to you. 22
